A dogs heat cycle can last up to 4 weeks and yes her vulva will remain swollen throughout. I have not really noticed or maybe just never paid much attention to the behavior of my girls when they were in heat so cant' say about the burst of energy thing.
When was the first day of her heat and is there any chance that you could be wrong or that she may have been in contact with an intact male?
